Paper Abstract

A simple but original high-pressure fiber-optic system was developed for transmitting optical data via fiber lightguides to and from the inside of a high-pressure vessel at up to 200 MPa. This multifiber system is fully demountable and can carry up to 20 independent optical fibers of different types and different diameters. The paper discusses the principles and the details of leadthrough system design and describes its performance using single-mode and polarization-maintaining fibers. Preliminary applications include new high pressure fiber-optic sensors as well as measurement of the transmission and/or reflection properties of solid or liquid materials under high hydrostatic pressure. The idea of a new high pressure sensor using highly birefringent bowtie type optical fiber is briefly out-lined.
